[PATCH 5.17 0188/1126] brcmfmac: pcie: Release firmwares in the brcmf_pcie_setup error path

From: Hector Martin <marcan@marcan.st>

commit 5e90f0f3ead014867dade7a22f93958119f5efab upstream.

This avoids leaking memory if brcmf_chip_get_raminfo fails. Note that
the CLM blob is released in the device remove path.

Fixes: 82f93cf46d60 ("brcmfmac: get chip's default RAM info during PCIe setup")
